Monitoring
The remote demodulator's value of Eb/No can be monitored at all times, either from the
front panel (MONITOR, AUPC) or via the remote control interface. The resolution of
the reading is 0.2 dB. For all values greater than or equal to 16 dB, the value 16.0 dB will
be displayed. As long as framing is enabled, the value will still be available, even though
AUPC may be disabled.
Also displayed is the current value of Tx power increase. If EDMAC framing is enabled,
but AUPC is disabled, this will indicate 0.0 dB. This value is also available via the
remote control interface.
CAUTION
Comtech EFData strongly cautions against the use of large values of
permitted power level increase under AUPC control. Users should
consider using the absolute minimum range necessary to improve rain-
